9.1.6 Checkerboard V1 Codehs Review

Example (pseudocode):

for r in 0..7:
    line = ""
    for c in 0..7:
        if (r + c) % 2 == 0:
            line += "#"
        else:
            line += " "
    print(line)

We solve the problem by:

Pseudo-code:

function start():
    turn off beeper auto-placement
    var row = 1
    while (front is clear or left is clear):
        placeRow(row)
        if (front is clear):
            moveToNextRow()
        row++

Using the parity rule (r + c) % 2 determines cell contents and yields a simple, provably correct O(n^2) algorithm. The provided textual and graphical templates adapt to typical CodeHS environments. If you supply the exact CodeHS problem text or target language/API (e.g., Java, JavaScript, CodeHS turtle), I will produce a tailored solution and classroom-ready explanation matching that context.

Problem: The squares are outlined but not colored.
Fix: You must call both setFillColor() and setFilled(true). 9.1.6 checkerboard v1 codehs

for row in board: print(row)

Alternatively, if you want a more visual representation:

# Initialize the board
board = []
